Overview: Memory. Whether it's sharp, fuzzy, poignant, or thrilling, it's the glue that binds our mental lives. Without it we'd be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are, and how we learn and navigate the world. But how odes it work? Luckily, 'NOVA: Memory Hackers' has all the answers.

DVD Verdict: The more you know about your memory, the better you'll understand how you can improve it. So, as witnessed in this captivating new PBS documentary, here's a basic overview of how your memory works and how aging affects your ability to remember.

Your baby's first cry...the taste of your grandmother's molasses cookies...the scent of an ocean breeze. These are memories that make up the ongoing experience of your life -- they provide you with a sense of self.

They're what make you feel comfortable with familiar people and surroundings, tie your past with your present, and provide a framework for the future. In a profound way, it is our collective set of memories -- our "memory" as a whole -- that makes us who we are.

So, here in 'NOVA: Memory Hackers' we discover how researchers on the cutting edge of mind-control can implant, change, and even erase memories. On this thought-provoking journey into the mind, NOVA investigates the mysterious nature of how we remember -- and sometimes why we don't. This is a Widescreen Presentation (1.78:1) enhanced for 16x9 TVs.
